The moon has a maximum angular size of roughly 0.5 degrees. On a normal lens, 50mm on a 35mm camera, the field of view is around 50 degrees, and the width of the moon, subtending an angle of 0.5 degrees, will be 100th of the width of the photo.
The moon seems much smaller in the photograph than it did when viewed with the naked eye. Since the moon always subtends an angle of 0.5 degrees, the image on the retina must always be the same. Clearly the problem is one of interpretation: its larger size is an illusion, a trick of the brain.
Interesting... but don't we experience size in relation to its surroundings? Isn't it therefore possible that the picture, as experienced by the eye, is cropped when we look at the moon?
Our eyes, if properly designed, surely come with a zoom function?
